We must start by recognizing the fact that there are proletarian nations as well as proletarian classes; that is to say, there are nations whose living conditions are subject... to the way of life of other nations, just as classes are. Once this is realized, nationalism must insist firmly on this truth: Italy is, materially and morally, a proletarian nation." (Report to the First Nationalist Congress, Florence, 3 December 1919)
